SUMMARY OF THE INVENTION

The GEN II Meter System of the invention comprises:

A method of powering a parking meter and various peripheral devices thereof such as a radio, vehicle detector and digital rate plate or other low power electronic display using a high energy density-low current battery to charge a rechargeable battery with lesser energy density. Using the above-described system with an additional photovoltaic solar panel to supplement the high energy battery or using the above system without the high energy battery and only the photovoltaic cell. Alternatively, using any of the foregoing above powering methods in conjunction with a non-rechargeable battery or batteries as a backup power source for parking meters or its peripherals.

The problem solved by the GEN II Meter System of the invention is that in prior art systems the power consumption limits the features available at a single space parking meter. Battery power can be used to meet the needs, but requires excessively frequent replacements of the batteries. Longer life (higher energy density) batteries and power sources exist, but have low current or non-linear output than is required by the electronics of the known parking meter system.

In the GEN II Meter System of the invention, by using a combination of one or more of the high energy density batteries with intermittent current as a means to charge higher current/lower density batteries with a “trickle charge” allows long life and higher current for powering remote electronics in parking meters. The electronics require power intermittently with long periods of low-no power consumption which allows the high current batteries to recover their charge during the low power requirement cycles.

In the GEN II Meter System of the invention multiple, interconnected microprocessors are used as a power saving methodology of parking meter systems having a plurality of features.

The problem solved is that power consumption limits the features available at a single space parking meter. Many low power microprocessors exist, but have limited capacity to manage operations.

In the GEN II Meter System using multiple low power microprocessors to perform specialized tasks and only “wake up” for the purpose of performing that specialized task allows for the system overall to consume less power without giving up processing capacity. Power is not wasted keeping processors “awake” when not needed.

The GEN II Meter System uses a specialized network topology for applications of radio transmissions between single space parking meters in traditional high-impact meter housings and a network operations center.

The problem solved by the GEN II Meter System is that single space parking meters rely on battery power to enable operation of the associated electronics. Radio transmissions require relatively high levels of power. Additionally, the thick metal of many hardened single space parking meter housings provide an additional obstacle to radio frequency transmissions. Many existing low-power radio systems rely on short range transmissions and “mesh” topologies to overcome this limitation. While such topology provides the benefit of allowing transmissions to succeed in the context of single space parking meters, it has a number of problems. First, regardless of the redundancy provided by standard mesh topologies, standard paths for data flow are established. These pathways converge for multiple individual parking meters as the data flow approaches the endpoint of a network segment. Network nodes closest to the segment endpoints experience unordinary higher periods of time in active communication with other nodes and consume large amounts of power. Second, mesh networks reach a limitation in the number of nodes that can be supported. While pure “star” topologies can solve this problem, they do not

The problem solved by the GEN II Meter System is that described for the “use of a Reed Relay” in paragraphs [0012] and [0014].

In the GEN II Meter System the problem is solved by the use of an alternate switch as described above except that a passive Radio Frequency sensitive coil is energized by radio waves to close the circuit to power the appropriate pin on the microprocessor. The source of the radio waves can be of any sufficient magnitude of radio waves directed at the meter including, but not limited to, a handheld device, a Radio Frequency wave generator in a collector unit or a passing vehicle.

In the GEN II Meter System of the invention a digital reprogrammable display allows dynamic display of parking policy information at a single space parking meter in a vehicle parking meter system.

In the GEN II Meter System a universal electronic parking meter interface allows a single peripheral device to communicate with any plurality of parking meters including two or more of the following commercially known systems: Duncan Eagle 2000 and 2010, POM APM, Mackay Guardian or any other parking meter from any other manufacturer.

In the GEN II Meter System a method allows a parking meter to be re-programmed or re-configured for various rates, time limits or hours of operation and other operational parameters including, but not limited to enabling the resetting of time upon a vehicle departure, enabling software that prevents s user's ability to add time to the meter beyond the time limit even if payments are received during multiple time frames of the motorists occupancy of the space and granting of free time upon a vehicle's arrival or the enforcement of different rates being charged for an occupant depending on how long they are in the space. Additionally, the Gen II meter system incorporates the ability to display changes in operating policy to users by means of a low power electronic display as described in paragraph [0018] affixed in the stead of a traditional meter's rate plate.

A problem of known parking meter systems is that any change in the operating parameters of a single space parking meter requires someone to physically visit each parking meter. In the GEN II Meter System of the invention the provision of a peripheral radio, operational microprocessor and connecting radio network, the peripheral radio communicates such changes to the operational microprocessor. The operational microprocessor, in turn, initiates a change in the logic for all the connected devices to establish the new operating parameters and updates of the displays on both the meter and the low powered electronic display as needed.

The GEN II Meter System of the invention provides a method that allows a merchant to purchase time at a parking meter for a patron by use of a web, cellular or other type of telecommunications medium in which the time purchased may also be posted to the meter monitoring the space in which the patron parked their vehicle.

The problem solved by the GEN II Meter System of the invention is that merchants wishing to attract new customers or improve the experience of potential customers may want to pay for the parking fees of such customers. In some cases, they may want simply to make a change. In either case, either the merchant or the customer must return to the parking meter monitoring the space in which they parked and initiate payments.

In the GEN II Meter System of the invention, by creating a readily available interface for a merchant through either a stand-alone device with a web, telecom or other type of network to a secured command And control interface as described in U.S. patent application Ser. No. 11/802,244 and entitled; Parking System Employing RAM Parking Techniques, a merchant and/or customer initiates payment from a location more conveniently located to the store. This interface will then initiate a signal to the meter monitoring the space identified as well as enforcement personnel that the space is paid for and, display the time purchased on the display of the parking meter as appropriate.

The GEN II Meter System of the invention provides a method to display time purchased by any remote payment system to an independent parking meter by use of a radio frequency network.

Another problem solved by the GEN II Meter System of the present invention is that payments made using systems disconnected from the parking meter monitoring the space for which payment is being made requires additional and error prone verification by enforcement personnel to avoid writing invalid parking tickets.

This problem is dealt with by the GEN II Meter System of the present invention by connecting the parking meter to a radio network, time can be posted directly to the meter by a centralized command and control interface (CCI). The CCI is similarly connected via any form of networking technology to the payment system including but not limited to telephone payment systems, internet payment systems, stand-alone kiosks and Point-of-Sale systems.

The GEN II Meter System of the invention provides an antenna specifically designed to optimize the communications of a radio to a centralized collector radio from within a hardened, single space meter housing.

The problem solved by the GEN II Meter System of the present invention is that hardened meter housings create unique radio frequency propagation and reflection properties for any radio contained inside.

In the GEN II Meter System a specific design for radios deployed in this manner can maximize the transmission range and minimize power requirements.

The GEN II Meter System of the invention provides a “State Machine” space status logic form to monitor and control a parking space and the various assets installed at that space as well as record a historical data stream reflecting the usage characteristics of the parking space.

The problem solved by the GEN II Meter System of the present invention is that low power microprocessors can not efficiently perform the complex logic needed to capture and respond to all of the various elements of managing a parking space in a linear manner.

In the GEN II Meter System of the present invention by, establishing the various elements of the state of a parking meter into various yes/no states and creating a matrix of instructions for the microprocessor to execute for the occurrence of any event in each of the various compilations of those states, the microprocessor can more efficiently react to events. Additionally, changes in the programmatic logic to be used by the microprocessor require updating only the matrix of instructions but not the detailed methods used to perform those instructions.

The Gen II Meter System of the present invention is adaptable to various forms of vehicle detection including, but not limited to induction loop, magnetometer, ultrasonic and/or doppler radar sensors. In all cases, the Gen II Meter system is most reliable when the components are deployed so as to avoid any interference from passing vehicular, pedestrian or other traffic and protected from potential vandalism.

The problem solved by the Gen II Meter System of the present invention is that while inductance loop vehicle detection remains the most reliable form of vehicle detection for monitoring the stationary vehicles in a parking space, installation of inductance loops may be impractical in certain situations. The use of other sensors has often been impractical by interference for movement and events outside of the intended monitoring space of the parking space being monitored. This is due part to the placement of monitoring sensors in “line of sight” of the space. If an object is placed or moves between the sensor and the space being monitored, detection errors can occur. Finally, many other forms of detection have shortcomings in terms of their ability to reliably sense a non-moving vehicle over long periods of time.

The Gen II Meter System of the present invention's preferred embodiment is that of an induction loop placed in the roadbed of the space to be monitored. If the preferred embodiment is not possible, a doppler radar sensor placed either in the roadbed of the space to be monitored and communicating via the wireless radio interface to the Gen II meter system node can be used. Both of these methods ensure that no interference from objects or events outside the space being monitored affect the detection and are able to reliably track the presence of stationary vehicle over the long term. The flexibility inherent in this design also allows for the use of any of the lesser sensor technologies should the preferred embodiments not be possible or feasible.

DETAILED DESCRIPTION

System Overview

The GEN II Meter System of the present invention comprises multiple task specific processors as shown in the Figure. The system is controlled by the Application Processor (AP) and the remaining devices are controlled via a shared SPI bus.

Processor Functions

The AP is a controller for the entire system and its functions include power management and monitoring, managing the state of the parking spaces, and controlling firmware upgrades. The Radio (RP) is essentially a pass-through communications device which passes messages from the AP to the collector and back.

The Meter Processor (MP) handles the communications to/from the parking meter, and the Vehicle Sensor Processor (VP) located on the circuit board provides information to the AP on the status of the sensor loop.

The components of the GEN II Meter System are mounted on a circuit board.

System Power

The system comprises a LiPo rechargeable battery, 3 AA primary cells and a solar panel. The system is powered by the LiPo battery which is recharged by the solar panel. The AA batteries provide backup power if the voltage on the LiPo battery drops due to lack of sunlight in a particular installation location. To enhance power efficiency each processor has its own voltage regulator that can be disabled by the AP to conserve power.

PCB Configuration

To allow maximum flexibility and the use of either 900 MHz or 2.4 GHz, the radio is designed as a daughter board mounted to the main system circuit board. The main sensor circuit board also attaches as a module to the main system board.

Mechanical Configuration

The entire PCB assembly, including the rechargeable battery, is designed to be permanently potted into an injection molded housing. The solar panel and AA battery holder are attached to the outside of the housing. Both a pigtail sensor cable and meter interface cable exit the housing for connection to the sensor loop and meter, respectively.

Power Control

To prevent the sealed rechargeable battery from being drained prior to installation, the system monitors the presence of the AA batteries. If no external batteries are installed the system remains powered down. Additionally, removal of the external batteries causes the system to power down after a set time period.

Tables 3a-3d—Examples of Stored Programming Event Handler Matrices

This collection of tables is actually an example of a single set of programming event handler matrix. This matrix shows along the left hand side the parking state the monitored space is in at the time the observed event is registered by various components designed into the Gen II system. The programming on the Application Processor (AP) then cross references both the event and the state currently registered for the space for an instruction set to enact various messaging to other component of the Gen II system and/or to initiate communications to be passed up to the centralized operational control system. This command set is a representation of one such set of instructions that could be compiled for the operation of a Gen II system. Additional states, Events and instruction sets could be added or changed to alter the operation of the system as policies change or new event types are defined.
